This is the first time I've played a VN without any character art whatsoever. At first I thought "ugh, this is just too cheap", but in essence, even with background art and music being there, it works more like reading a book. As in, your mind will simply create the characters or their looks for you in your head while reading. I'm surprised that the lack of portraits didn't bother me too much in the end. It still just kinda works.
Also, I do like the girls, they're pretty interesting.
Haven't played all routes yet, but I think it's safe to say: Not so bad after all. :)
Ah, and this is also the first VN ever which I found to be available as an .apk file for Android. Also tested it briefly on my Blackberry KeyOne using Android 8.1, and yep, it works fine! :)
